Though russia fell with the czars? infact wasnt there family not even russian?
Both of these things are true. The early Bolsheviks actually despised Russia, Russians and what they described as 'Great Russian chauvinism' -
they had put in place proto-affirmative action & other policies designed to benefit the non-Russian nationalities at the expense of the actual Russians and
a lot of their rhetoric around the subject sounded very much like modern wokies raving about the evils of American/Christian nationalism & how it's critical to deconstruct Amerikkka to rebuild Turtle Island in its place. (While a lot of said Bolshies were infamously Jews and their greatest military muscle came from the Latvians, you can also find comments from actually Russian Bolsheviks like Bukharin which sound like they could've come from a self-hating white prof today.) This sort of crap mostly died down under Stalin (because he realized Russian nationalism, Orthodoxy, etc. would be helpful in combating the Nazi threat).
As for the Romanovs, their ethnically Russian male line of descent died out in 1762. Starting with
Peter III (who was such a yuge proto-Kaiserboo that he pulled Russia out of the Seven Years' War right when they had Prussia on the ropes, a 'miracle' which Hitler hoped would repeat itself ~200 years later, and got assassinated by his wife Catherine the Great - also a German - shortly afterward), the tsars were technically Germans of the House of
Holstein-Gottorp-Romanov. This became an actual problem for Nicholas II, one of the many reasons as to why he lost popularity was that there was great popular paranoia that his German-born wife Alexandra was plotting to betray Russia to her kin (her brother Ernest Louis, Grand Duke of Hesse, was a general in the German army) and he might've been in on it himself (Kaiser Wilhelm was his cousin and in 1915 he had made the disastrous decision to take personal command of the Imperial Russian Army, which then kept on losing battles & retreating for the most part). Also Baltic German nobles were hugely influential in the higher echelons of Russian society and the military, which is why you had generals with last names like Von Rennenkampf, Wrangel, Von Lieven, etc. running around as late as WW1/the civil war.
Arguably the last gasp of authentic Russian nationalism was on the White side of the civil war, where their generals at least actually regularly spoke Russian (French was the preferred language at the Russian imperial court, and Tolstoy's
War and Peace among other works cast light on a lot of Russian nobles knowing only enough Russian to command their servants) and their overall top leaders Kolchak & Denikin were so autistically fixated on their motto of 'Great Russia, one & indivisible' that they refused to work with the Finns & Poles (who were trying to gain independence from Russia at the time) even when the latter could've helped them beat the Bolsheviks. That Russian nationalism was such a strong motivator for the White Russians was also one of the reasons why the Bolsheviks tried so hard to extinguish it (besides, of course, simple loxism intensified by the antisemitism in the old Russian Empire being a lot worse than Fuentes types being platformed).
Anyway that's enough history sperging out of me, Merry Christmas and God bless us everyone!
